if you think about it the thermostat stays closed til temp gets 195 then opens so coolant stays in radiator longer to cool , 180 opens 15 degrees sooner,and cant cool radiator down.
atleast thats how i look at it..
If you think about it, that is not how thermodynamics of fluids work. That's not how any of this works. Period. Less time in the radiator is offset by more fluid passing through in a given time.
This urban legend/myth has been popping up for the 40+ years I've been turning my own wrenches and I just can't understand why it keeps coming back. Forget "doesn't have enough time to cool".
